Straight lines are 180 degrees and angle BCD is 110 degrees, and also AB and CB are the same which means 180-110=70 and 70 divided by 2 is 45 degrees so m angle A =45 degrees and m angle B= 90 degrees and ACB is 45 degrees
Answer:
x=5
Step-by-step explanation:
4x+8=2x+3x+3
2x+3x=5x
4x+8=5x+3
-4x
8=1x+3
-3
5=1x
5/1
x=5
Density is the measurement of the amount of mass per unit of volume.
In this case we should calculate the density of prairie dog burrows on a square field. This is a surface charge density.It is defined as the total amount of units q per km^2.
to calculate<span> the </span>density of prairie dog burrows, we should divide the total number of prairie dog burrows in the field <span>by the size of the field. Thus,
</span><span>
</span>prairie dog <span>burrows in square kilometers= number of dog burrows/ size of the field
size of the field=0.9*0.9=900*900=180000m^2
1980/180000</span><span> m^2= 0.011 dog burrows in square meter
11 dogs in square kilometer</span>
There are 8 nickels and 26 half dollars.
26/2=13
8*5= 40
Answer:
-2/7
Step-by-step explanation:
2x+7y=14
7y=-2x+14
divide by 7
y=-2/7 x+2
